Yet most people in Northern Ireland still seem to want to remain part of the United Kingdom. A BBC poll earlier this year suggested that just 17% of people in Northern Ireland want to leave the United Kingdom.
Dry ice is made from carbon dioxide gas. The carbon dioxide gas is pressurized and cooled to form liquid CO 2.The liquid carbon dioxide is injected into either a block press or pelletizer. These dry ice production machines have chambers in which, once released to atmospheric pressure, the liquid carbon dioxide converts to dry ice snow and carbon dioxide gas.he carbon dioxide gas is pressurized and cooled to form liquid CO 2.

Answer: Dry ice is the common name for the solid form of carbon dioxide. Originally the term ' dry ice ' was a trademark for the solid carbon dioxide produced by Prest Air Devices (1925), but now it refers to any solid carbon dioxide. Carbon dioxide is a natural component of air.Dry ice is safe to use for smoke machines and lab experiments, providing care is taken to avoid frostbite.ry ice is made by compressing carbon dioxide gas until it liquefies, which is at about 870 pounds per square inch of pressure at room temperature.
